no microphone capture - intel ICH9 AD1884


Hi to all.

I'm having problems with my soundcard in ubuntu 8.10. The sound is not captured, whereas everything else is working properly. This is the data on my soundcard

Code:
$cat /proc/asound/card0/codec#* | grep Codec
Codec: Analog Devices AD1884
Code:
$lspci -v
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)
Subsystem: Hewlett-Packard Company Device 281e 
Flags: bus master, fast devsel, latency 0, IRQ 21
Memory at f01a0000 (64-bit, non-prefetchable) [size=16K]
Capabilities: <access denied>   
Kernel driver in use: HDA Intel                          
Kernel modules:snd-hda-intel
I already tried to put "3stack" as an option in /etc/modprobe.d/alsa-base but this does not seem to work.

Any suggestion?
Thanks in advance

Use 'alsamixer -V all' to get more settings. While alsamixer is running, use audacity or the command 'arecord | hexdump' to test if it is capturing. During the recording, start adjusting mixer settings in alsamixer to get the sound card to capture audio.

Thanks Electrofor your advice.
I already played around with all alsamixer settings but without any success. I guess the solution is a bit more complicated that that.

Alsamixer is not very intuitive, but assuming you have tried all the possibilities there it is worth checking the file

Documentation/sound/alsa/ALSA-Configuration.txt

in the kernel source for any tweaks relevant to your sound interface. For example I found "model=6stack-hp" in the alsa-base file fixed my problems, even though the hardware was nothing to do with hp. (Since then the kernel code has improved the extent I don't need it anymore.)

Ok, I looked at this file and found

Code:
	Model name	Description
...
	AD1884A / AD1883 / AD1984A / AD1984B
	  desktop	3-stack desktop (default)
	  laptop	laptop with HP jack sensing
	  mobile	mobile devices with HP jack sensing
	  thinkpad	Lenovo Thinkpad X300
	AD1884
	  N/A
does this mean that there is no (not yet) support for my soundcard?

Sorry, I don't know the answer to that. Perhaps you could try the options for those closely related chips. I can see you've got the latest Ubuntu distro. Is the m/b a new model? Often it takes several months for support to arrive, but the kernel doc is probably the place to look for it (except for Google of course).
